Abstract
L'invention porte sur une lentille prismatique (10) comportant une pluralité de prismes (60) formant un bloc entourant une zone centrale non prismatique (90) orientés sommet (72) vers l'intérieur et base (62) vers l'extérieur. Chacun des prismes (60) est contigu ou en contact avec deux autres prismes (60) de manière à ceinturer la zone non prismatique (90). L'invention peut comporter des éléments lenticulaires (30) coniques, sphériques ou asphériques. De plus l'ensemble des prismes peuvent être disposés du côté objet (12) ou du côté image (14) de la lentille (10), pour permettre d'obtenir une courbure prescrite avec des éléments lenticulaires (30) soit du côté objet (12), soit du côté image (14) de la lentille (10).
